I know many won't agree, but I personally like 10X's binos, and a 80mm soptting scope. ( I currently use Leica, but hope to move on to Swarovski.) But when It comes to glass, at least in Alaska, the extra weight saves me more miles. I used to use a 65 mm spotter, and I wouldn't go back to it if you paid me. For me seeing that lamb tip on a ram and being able to draw a bit sharper focus to judge a brown bear that is 3 miles away, makes ALL the difference.
If I were only sheep hunting maybe 8X32 on the binos, but for moose, brown bear, you sit alot, and thus 10x's are the way to go.
Hunting elk and Mulies out West, I have to once again vote for the 10's, I think the extra magnification makes up for the weight once you sit for a while to glass. If you can't see it you will never shoot it, and spotting animals is all about finding contrast.
Though it is probably worthless, that's my 2 cents.
